Two different series of patients with Infectious Endocarditis (IE), hospitalized in the same ward of Curry Cabral Hospital in Lisbon, are presented and compared. The two series were separated by a ten-year period--the first included patients observed from 1970 to 1976 and the second from 1988 to 1998. In the first series (20 patients), IE occurred mainly in patients with previous cardiac valvular lesion, the course was subacute and Streptococcus viridans was the predominant agent. In the last series (65 patients), most of the patients were young and had no previous valvular lesions. Right side endocarditis predominated and the course was acute. Most of patients were drug addicts and had HIV infection. Staphylococcus aureus was the predominant agent. The ages of the two series were significantly different (p < 0.005). The diagnostic value of transthoracic and transesophageal echocardiography is stressed. The details of the evolution of patients with HIV infection are presented according to the values of CD4+ lymphocyte counts. The relatively good prognosis of IE in drug addicts with antibiotic treatment, even with HIV infection, is emphasized.

The superior performance of stentless aortic valves with improved left ventricular hypertrophy regression and greater effective orifice area is proven. The Aortech Elan stentless valve (AESV) is a glutraldehyde preserved porcine valve with a pericardial reinforced inflow tract and a scalloped outflow to reduce bulk. We present the early results of AESV implantation at our institution. The first 41 consecutive recipients of the AESV at our unit, between November 1999 and December 2000, were studied. Mean preoperative New York Heart Association functional class (NYHA) status was 3.00 +/- 0.1. Patients requiring a bioprosthesis with suitable anatomy routinely received this implant. The AESV was implanted, either with an interrupted or continuous suture to the inflow tract and a continuous suture to the outflow tract. Transthoracic echocardiography was performed at 6 to 9 weeks after surgery, and aortic transvalvular gradients, flow velocities, and effective orifice areas (EOA) were calculated. In the early postoperative period, two patients with coronary artery disease died of low cardiac output. Echocardiography demonstrated competent valves. At follow-up, one patient was shown to have mild to moderate perivalvular leak with minimal symptoms. Two patients with aortic regurgitation secondary to bacterial endocarditis had no evidence of infection at 3 months after surgery. Mean transvalvular gradient was 6.91 +/- 0.87 mm Hg and mean effective orifice area was 1.18 +/- 0.04 cm(2)/m(2) at a mean of 8.4 weeks after surgery. AESV recipients for native aortic endocarditis were free from infection and regurgitation. The Elan stentless aortic valve demonstrates excellent early hemodynamic results, with very low transvalvular gradients, good flow characteristics and low regurgitation incidence. Ease of implantation is evidenced by favorable ischemic times. This valve may offer an option to homograft in acute aortic endocarditis. Long-term results are awaited.

A 59-year-old patient developed endocarditis with coagulase-negative staphylococci after aortic composite graft replacement and pacemaker implantation. She underwent complete pacemaker removal and tricuspid valve reconstruction. Pus was present in and around the aortic graft. Re-replacement of the aortic root and ascending aorta using only biological material was performed. A 23-mm full root stentless prosthesis (Vascutek Root Elan, Vascutec, Terumo, Leeds, UK) was used for aortic root replacement, and a second 25-mm full root prosthesis with removed cusps implanted in a reversed fashion was used for ascending aorta and proximal aortic arch replacement.
